Horse Hay-Bake.

JAMES E. VISNER, OF FRIENDSHIP, NEW YORK.
IMPROVEMENT IN HQRSE .HAV-RAKES.
Specification forming part of Letters Patent No. 162, 132, dated April 13, 1875; application tiled i August l, 1874.
To all whom it may concern:
Be it known that I, JAMES E. WISNER, of Friendship, in the county of Allegany and State of New York, have invented certain new and useful Improvements in Horse Hay- Rakes; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanyin g drawings forming part of this specitication, in which- 1 Figure l is a longitudinal section of a horse hay-rake, constructed in accordance with my invention. Fig. 2 is a partial plan view. Figs. 3 and 4t are devices showing the method of securing the teeth to the thimbles ofthe axle; and Fig. 5 is a rear view of the spring and guide for the detent, applied to the lifting-bar.
Similar letters of reference indicate corresponding parts in the several igures of the drawings.
My invention relates to that class of horse hay-rakes in which the hay is automatically dumped by the draft or power ot' the team, at the will ofthe operator; and has for its object to simplify the construction and operation of the same.
It consists, first, in the combination of a guard which also performs the function of an 'adjustable tripping device, with the ratchetwheel, to prevent the teeth of the latter from catching the cut hay or grain during the operation of raking.
It also consists in the means of attaching the rake-teeth to the axle, as hereinafter more fully set forth.
In the accompanying` drawings, A is the axle, secured to the driving-wheels B B, so as to revolve therewith; and G C are the thills, hung upon the axle between the wheels by any suitable means which shall not interfere with its rotation. The thills are connected near their rear ends, in front of the axle, by means of bars D D, to form the rake-frame and support the driveis seat E. F is a ratchet-wheel, secured to the axle at or near the center, so as to revolve therewith, and having its teeth curved or inclined forward. G is the lifting-bar, held in rear of the axle by means of the arms H H, and provided with guide-loops for the passage of the raketeeth J. Instead of employing the staples or loops for supporting the teeth, the latter may be passed through vertical slots formed in the lifting-bar. These slots should be sufficiently long to permit the vertical play of the teeth, and sufficiently wide to admit of a slight lateral movement. K is a forked or bifurcated arm embracing the rear half of the ratchetwheel and connecting the lifting bar with the axle,being fitted loosely upon the latter. A right-angular detent, L, is pivoted within the forked arm,in rear ofthe ratchet-wheel, so that its lower arm shall extend througha guidestaple, M, depending from thelifting-bar, and so that its upper end shall extend above the ratchet-wheel. The vertical portion of this lever is provided with a hook, N, to engage with the teeth of the ratchet-wheel, and is connected by a chain, O, to the seat-standard or other part ofthe rake-frame. A spring, P, on the guide-staple presses down the lower arm ot' the detent, to hold the hook out of contact with the ratchet-wheel.
I do not confine myself' to this precise construction of the detent, as it maybe composed of a simple upright hook-bar, held out of contact with the ratchet-wheel by a coiled spring extending from its upper end to the top ofthe lifting-bar. By this construction, of course, the guide-staple and its spring are not required. Q. is a curved metal plate arranged upon the rear bar D of the thills, immediately in front of the ratchet wheel, and adapted for vertical adjustment by means of the screw-bolt It, or other suitable device. rlhe rake-teeth are each att-ached to separate thimbles S, mounted loosely upon the axle, as shown, and are secured to the said thimbles in the following manner: The center of each thimble is cast or otherwise provided with a U-shaped rib, T, having a groove in its curved `edge-that is to say, a groove extending along the top front and bottom sidesby which the tooth and thimble are kept in the same relative relation. The forward ends of the teeth are curved, as shown in Figs. 3 and 4, and passed around the rib so as to lie within the groove.
position they are held either by a pin or bolt, U, placed through the lugs V, in front of the tooth, as shown in Fig. 3, or the extreme end of the tooth is provided with a similar pin or 1u uns bolt in rear oflugs WV, as shown in Fig. 4. By removing the pin or bolt in either case, the teeth may be readily takenl ott' of the thimbles when occasion requires. When the rake is in operation and it is desired to raise the teeth for the purpose of dumpingthe hay into a windrow, the driver presses lightly with his foot upon the chain 0, to engage the hook end ofthe detent with the teeth of the ratchet-wheel. As the rake moves forward the rotation of the ratchet-wheel lifts up the detent, which in its turn raises the'lit'ting-bar and teeth until the top ot' the detent comes in contact with the upper end of the curved plate, and disengages the hook from the ratchet-wheel, when the teeth fall back by their own gravity into a position for raking. By adjusting the curved guide higher or lower, the distance between its upper end and the detentislengthened orshortened, and therefore regulates the height to which the teeth may he raised, as well as the length of time they are held in an elevated position. This constitutes a very important feature of my invention, since it adapts the teeth to be raised higher and to be held longer in their raised position when the rake is working in heavy hay than in thin hay. That is to say, by ad-V justin g the guide downward the space between its upper end and the detent is increased7 so that when the teeth are elevated they are carried high enough to clear the largest windrows. By adjusting the curved guide upward, the space between its upper end and the detent is decreased, thereby limiting the upward movement of the teeth. The capability of adjusting the throw of the rake-teeth adapts the rake for use in the formation ot' gavels from cradled grain, necessary that the rake shall operate quickly, its teeth being raised just high enough to clear the gavels and drop over them into the swath. By adjusting the curved guide these results are accomplished which enables the teeth to rise or fall rapidly. 1t will be observed that the arc through which the pivot of the detent moves is concentric with the rakeaXle, the ratchet-wheel, and the path of the lifting-bar, so that the various parts are prevented from being bound or cramped during the operation of raising and dumping theload.
Having th us described my invention, what I claim as new is 1. The thimbles S S, mounted loosely on the axle, andprovided with the grooved U- shaped ribs T, having lugsV V, in combination with the rake-teeth J and bolts U, substantially as described, and for the purposes set forth.
2. The combination of a hooked detent, connected to the lifting-bar, with the ratchetwheel on the revolving rake-axle, and the adjustable tripping device on the frame of the rake, substantially as described, for the purpose specihed.
3. The curved plate Q, adapted to form a guard for the ratchet-wheel, and an adjustable trip for the lifting device, substantially as described.
